Improvement in cork-presser

. IMPROVEMENT IN CORK-P RE SSER.

The Schedule referred to in these Letters Patent and making partial the same.

To all whom it maycoucern:

Be it known that I, J AMES EWING, of the city and county of New York and State of New' York, have invented a new and improved Cork-Presser; and I do hereby declare that the' following is a full, clear, and exact description thereof, reference being bad to the accompanying drawing making part of this specification, in which- Figure '1 is a side elevation of the improved corkpresser, showing a cork adjusted in position preparatory to being compressed.

Figure 2 is a similar viewot' the same parts, sho.wing a cork in the act of being compressed.

Figure 3 is a section through the instrument, taken .in Elle vertical plane indicated by the dotted line a; :r, in g. 1.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to improve corkpressers, by the employment of a rotary cam or scrollpress'er, in combination with a concave bed, between which plates corks of different diameters can be compressed and made smaller by rolling actiomas will be hereinafter explained.

Toenablc others skilled in the art to understand my invention, I will describe its construction and operation.

The improved instrument consists of two parts, to wit, a cam-wheel, A, and a concave bed, 0, which parts are preferably made of metal cast in the form substantially as shown in the drawing. The cam wheel consists of a rim having a broad and flat external surface, and connected to a hub by means of spokes. The inner side of the rim may be rounded, so that it can he firmly grasped in the hand. This cam-wheel A presents a scroll periphery and an abrupt concavity, b, and it is connected to the side of a vertical standard, I), by meansof a short shaft, a.

The standard D rises perpendicular from the back part of a concave bed, 0, which bed may be concentric or eccentric to the axis of shaft a, and which is equal in width to the periphery of the cam A, as shown in fig. 3. This bed is constructed with aflange or ridge, (1, along its back edge, the object of which is to serve as an abutment for the ends of the corks,

to prevent them from being inserted too far beneath the cam. The bed and standard are constructed with a wide base support, which is perforated to receive through it one or more screws or nails, by which the instrument can be secured either to an established object or to a portable one.

Corks are condensed in this instrument by adj usting them, one ata time, between the periphery of the cam A and the surface of the, bed 0, and then oscillating the cam, at the same time adjusting it so as to cause its periphery to approach nearer to the bed.

In fig. 1 a cork is shown in position between the 'cam and bed, for commencing the operation of rollingand pressing it, and infig. 2 the cork is represented in the act of being pressed.

It will be seen from the above description that the I corks are rolled during the application of pressure to them, and thus made round or cylindrical; also, that the instrument is adaptedfor corks of different sizes.

I do not claim the principle of compressing objects by means of two gradually-approaching surfaces; nor do I claim forming taper bungs nor cylindric dowels or tenons by machines constructed to operate onthe principle shown in patents granted to Benjamin D. Saunders, June 1, 1869, and March 29, 1870; but

\Vhat I do claimas my invention, and desire to secure byLetters Patent, is-- I he within-described cork-pressing device, constructed and operating substantially as set forth.
